DBUB'E-SUEZGRTING DEVICE.

application filed July 22, 1925.

This invention relates to improvements in musical instruments, and has particular rei? erence to a support for large or bass drums.

An object of the invention is to provide an improved device capable of being easily and quickly attached to a drum in such manner that when said orum is supported in a ver-- tical position the same will be prevented from rolling.

An object is to provide a support for the drum which will not become detached or loosened due to the vibrations imparted to the drum when the same is being played.

A further object is to provide a spur so constructed that when the same is not in use it may remain attached to the drum and be adjusted thereon so that the spur will not project beyond the periphery of the shell of the drum.

The above and other objects will appear more clearly from the following detailed description, when taken in connection with the accompanying drawing, which illustrates preferred embodiments of the inventive idea.

In the drawing Figure 1 is a front elevation of the drum showing the same supported in vertical position by use of the device of the present invention;

Figure 2 is a vertical transverse section through the drum illustrating one form of the invention wherein two pairs of spurs are employed for supporting the drum;

Figure 3 is a view similar to Figure 2 illustrating a slightly different form of the invention in which only two spurs are utilized for supporting the drum;

Figure Q is a fragmentary front elevation of the drum showing the inoperative position of a spur when the same is attached to the drum; and

Figure 5 is a fragmentary vertical section illustrating the spur in its inoperative posi tion.

Referring more particularly to the drawing, the numeral 6 indicates the shell of a large or bass drum which is adapted to be supported in a substantially vertical position when being played. It is a customary practice to utilize spurs for supporting the drum in this position to prevent rolling thereof and usually the spurs are attached to the shell of the drum at such positions that the portion of the shell intermediate said spurs will either contact or be spaced a Serial No. 45,206.

very slight distance from the floor or sup-- port.

in if res 1 and 2, two sets or pairs of spurs 7 are utilized and the spurs of each pair are attached to the edges of the shell 6 at opposite points thereon. Each spur con sists of a pointed shank the free extremity of which is adapted to engage the floor or other support, and. the other end of the shank being formed with a head 8 having the oppositely disposed aws 9 and 10 capable of receiving therebetween the edge of the shell 6, the distance between the jaws being substantially equal to the thickness of the shell, as clearly shown in Figure 2, so as to afford a tight lit. The head 8 is provided with longitudinally extending slot 11 extending between the jaws 9 and 10 and the jaw 10 is formed with a groove 12. Said groove is designed to receive an eye bolt 13 adjustable longitudinally of said groove for a purpose which will presently appear. The outer end of the eye bolt is partially threaded with the outer extremity 13' smooth and provided with ahead 14: to prevent detachment of the wing nut 14 from the bolt. Said wing nut is engageable with the head 8 to retain the spur and said eye bolt in position.

The eyes or inner ends of the bolts 1-3 associated with. each pair of spurs are connected by a flexible element 15 such as a chain or the like, one end of said chain being provided with a hook 16 permanently attached to one of the eye bolts. lVhen the supporting device is in position the intermediate portion of the chain, which is of a greater length than the d stance between the two eye bolts, is extended through the eye of the bolt opposite to which the hook 16 is attached and the other extremity of said chain carries a hook 1'? which can be engaged with any one of the links of the chain so as to support said chain in a tautenod condition. After thus adjusting the chain 15 the wing nuts 14 are turned inwardly against the heads 8 thus drawing the eye bolts 13 outwardly and thereby further tightening the chain 15 to aid in retaining the spurs 7 in proper position.

in the form of the invention shown in Figure 3. instead of employing two pairs of spurs. only two spurs are used and with eacii of them there is associated a. hook 18 linked to one endv of the chain 15 and en- 1 with an edge of the shell 6 in the same manner that the spur is attached thereto. Vith this construction it is necessary that the drum be supported in its vertical position by actual contact with the floor, the two spurs employed then engaging the floor in the same manner as illustrated in Figure 1.

Vith either of the two forms of the'inven-- tion the supporting device may be detached from the drum and due to the fact that a chain is employed for connecting the spurs,

' wing nuts the same will become disengaged from the screw threads of the bolts 13 and finally engage the smooth portions'13 at whichtimethey maybe slid out wardly withoutturningthus facilitating. the operation of both. loosening and tightening the wing nuts. Owing to the longitudinal slot 11 in each'ot' the spurs the same may be again engaged with the peripheries of the shell 6 with the. bolts 13 at the end of the slot op-. posite the one in which it is disposed when the spurs are in operative position. The wing nuts may then again be tightened to retain thespurs in their adjusted positions.

WVhat. is claimedis:

1. In a, drum supporting device, a spur capable of=attachment to. one side of the shell of a drum, anadjustable element car ried by said spur and movable transversely thereof, a fastening member carried by the opposite side of said shell, a flexible connection having one end connected. to said fas= In loosening the tening member, an intermediate portion thtereotextending through said adjustable element and its other end capable oi attachand means on said eye bolts engageable withthe spurs to move the eye bolts relative to the spurs and tauten said flexible element.

3. In a drunrsupporting device, a pair of spurs each including a head having opposed jaws for receiving, the periphery oil? the drum shell, said head also having a slot and one of said jaws having a groove therein, an eye bolt extending longitudinally in each groovev and projecting through each slot, a chain joiningsaideye bolts, and wing; nuts on the eye bolts engageable with the heads of said spurs-for tautening said chain.

4. In a drum supporting device, a spurv capable of attachment to the shell of a drum, an eye bolt carried by said spur and having a screw threaded portion and asmooth portion, a flexible element connected to saidv eye bolt, means also carried by the drum to which said flexible element is also connected, and a. wing nut on the threaded portion of said eye bolt engageable with said spur to tighten said flexible element, said wing nut capable of being unscrewed and engaged on.

said smooth portion of the eye bolt to permitsaid spur-to be reversed with respect to said drum.

In testimony whereof I have allixed my signature.
